Glazing Configurations
All types and configurations are available to use in Duratherm windows and doors. From single monolithic to triple glazing, laminated, curved-in-place, electrochromatic switchable – virtually any type or configuration commercially available – and perhaps even some that are not.
Glazing Methods
Dry Glazing
Specially developed extruded silicone gasket sets the glass by compression. Our proprietary system is long-lived, has low maintenance, and stays water resistant.
Wet Glazing
Our special silicone wet glazing compound bonds to the glass for long-lived sealing. Plus our continuous extruded silicone weatherstrip runs around the frame perimeter, and the seal is not compromised by seasonal expansion and contractions of the sash and frame.
